For Final Fantasy II specifically, I would instead recommend the PSP version. Given how experimental its leveling system is, to use and abuse of it properly, the PSP and the (now delisted) OG Android version are the best ones, as they have more contents to keep the player entertained, instead of being just a grind galore, as well as offering far more options as to how to break the game to the player’s advantage.
